ALFRED T. FOWL-ES,

OF DALLAS, TEXAS.

ATTACHING-RING.

Application filed June 13,

To all whom it may concern:

Be it known that I, ALFRED T. FowLns, a citizen of the United States, residing at Dallas, in the county ot Dallas and State of Texas, have invented certain new and useful Improved irttaching-Rings, of which the following is a specification.

This invention has for its object to pro vide an improved two part ring for connection with a boiler and the upper terminal of the jacket or casing of a water heater of the type disclosed in my co-pending applica tion for patent for water heater filed June 18, 1919, Serial No. 304;,0-11, which may be conveniently applied to the boiler and jacket and is attractive in appearance.

Another object is the provision of an attaching ring of this character which provides a tight joint between the jacket and boiler.

With these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction, combination of elements and arrangement of parts which will be more fully described in the following specification and set forth with particularity in the claim appended hereto.

Figure 1 represents a side elevation, partly broken away of the improved ring and a boiler and jacket,

Fig. 2 represents a plan view of the ring, and,

Fig. 3 represents a fragmentary perspective view of one terminal of one of the ring sections.

Referring to the drawings in detail, where in similar reference characters designate corresponding parts throughout the several views, the numerals 5 and 6 indicate the companion ring sections which are identical in shape and construction and are adapted to be coupled together to provide a circular ring to surround and inclose the upper Specification of Letters Patent.

edge of the jacket of a water heater as shown in Fig. 1. Each section includes a downwardly flaring flange 7 adapted to overlie and snugly fit the restricted upper ter mlnal of the jacket 8 and provided in its body portion with an internal circular groove 9 adapted to receive a packing ring whereby when the semi-circular sections are brought into engagement with the outer surface of a boiler whereby atight joint is pro vided. The adjacent terminals of the sections are provided with ears 10 having horizontally registering apertures therein for the reception of a bolt 11 carrying a: nut 12 by which the sections are brought into snug engagement with the boiler and jacket.

In use, the jacket 8 is applied to the boiler and the sections 5 and 6, subsequent to the removal of the bolts 11 are applied over the top edge of the jacket and in snug engagement with the outer surface of the boiler. A packing ring such as asbestos or the like is placed in the groove 9 and bears against the boiler. The bolts 11 are subsequently inserted through the registering apertures of the ears 10 and by advancing the nuts 12 upon the screw threads of the bolts the sections are brought and retained in firm engagement with the boiler thus forming a closure for the joint between the boiler and the jacket.

What I claim is:

A two part clamping ring formed of separable sections and with an internal, annular groove adapted to receive packing between the ring and the exterior surface of a boiler, and a downward, flaring flange depending from the ring and considerably below the groove, and alined apertured ears integral with the ring receiving bolts, securing the separable ring sections.

In testimony whereof I aflix my signature hereto.

ALFRED T. FOWLES.
